The present invention relates-tea fin type radiator and-moreparticularly to a fin type radiator such as used in 'the"ho't-'w'aterorsteam heatingsystem'ofa-house; T f Conventional fin'type radiatorscomprise a plurality ofparallel fins or thin plates preferablyofrectangularshape,- mounted transversely of one or more heating fluidconducting tubes and maintained thereon in spaced relationship by beingwelded or otherwise secured-at two opposite ends to suitable side platesextending at right angles to said fins; Such aconstruction is necessarytoprevent bending of long radiators and also to protect the fins fromdamage duringtransit .or inuse.

Because-"the; :fins of such radiators are relatively closely spaced,welding of each of saidfins to thef side plates requires a" relativelyconsid- 'erable amount of "work, and therefore-only a limited number'ofsaidfins are welded in practice. 'j" Therefore, after a' certain period:of use,

2 Claims. (Cl. 257-26246) preferably of rectangular shape and made of or'due todamage in handling, one or'more fins are liable to becomeunequally spaced or to come into contact one with the other therebydiminishing considerably the heat radiating efliciency of the fin typeradiator and marring its appearance.

Accordingly, the general object of the present invention is theprovision in a fin type radiator of means to prevent the above mentioneddrawback.

A very important object of the present invention is the provision in'afin type radiator of means for maintaining the fins in spaced positionwithout the requirements of side plates and of the welding operationsreferred to hereabove.

Still another important object of the present invention is the provisionin a fin type radiator of means for maintaining the fins at a constantsubstantially equal distance one from the other.

Still another important object of the present invention is the provisionof a fin type radiator in which all sharp corners have been eliminated,thereby preventing possible injuries especially during handling.

Still another important object of the present invention is the provisionof a fin type radiator provided with means for imparting to the fins andconsequently to the finished radiator considerably increased rigidity.

Still another important object of the present invention is the provisionof a fin type radiator of improved and yet very inexpensiveconstruction.

The foregoing and other objects according to the present invention willbecome more apparcut; during the following disclosure and byreferring tothe drawings in which:

Figure 1 isa perspective view of a fin type radiator according to thepresent invention; Figure 2 is a perspective view of one of the finelements according to the invention; I FigureB 'is a plan view of thefin type radiator;

V Figure 4' is a cross-section along line 4-4 of Figure 3;and' I"-Figure' 5 is a fractional enlarged plan section "of the fin elementsaccording to the invention. Referring now more particularly to thedrawings in which like reference characters indicate like elementsthroughout, the letters A and B denotes two heating fluid tubularconduits disposed in spaced parallel'r'elationship.

' [These conduits maybe connected in series so that; for instance, theconduit B will serve-as a return for conduit A.

A'plurality of -thin plates or; fin "elements I,

good heat'conducting material are each provided with a pair of spacedcircular openings 2 provided with a cylindrical flange 2 for receivingthe conduits A and B.

The flanged openings 2 have substantially the same diameter as theexternal diameter of said conduits so as to provide good contact betweenthe latter and said plates.

The fin elements I have substantially the same length and width, and theopenings 2 are equally spaced from the end and side edges respectivelyso as to provide alignment of said edges when the fin elements I aremounted on the conduits A and B to form the radiator according to theinvention.

The fin elements I are maintained in spaced parallel relationship acrossthe tubes or conduits A and B by means of the flanges 2 the outer edgeof which abut the next fin element along the edges of the openings 2thereof, and by means of the opposite end portions 3 of said finelements 1 which are bent at more than right angle so as to be inclinedrelatively to the surface of said fin elements and to contact the nextfln element along a line spaced from the edge 5 of the latter. 7

More particularly said line is constituted by a groove 4 made in saidfin elements. The free edge of said end portions 3 enters said groove 4and rests squarely against the bottom thereof thereby preventing furtherbending and collapse of said end portions 3 upon any outward pressureexerted on the fins.

It is very important that the end portions 3 be bent at more than 90 soas to rest squarely on the adjacent fin, thereby providing veryefficient means to maintain the fin elements I at a constant distanceone from the other.

In this manner there will be no possibility of one of the fin elementscontacting an adjacent one to decrease the efiicient radiating surfaceor mar the appearance of the radiator according to the invention. a

It Will be also noted that because the end portions 3 are turnedinwardly from the ends of the radiator, no sharp edges project out fromthe same which might cause injury, more particularly in transit. 'In thesame manner the end fin element I is provided with rounded end edges.

Whichcannot cause injury, its opposite end portions 3 being bentinwardly flat against its surface.

The fin elements I being preferably .madeof thin sheet metal material,it is necessary to provide the same with integrally formed ribs 6extending parallel'and spaced from the long sides 1 thereof, therebyimparting-improved rigidity thereto. a

- The ribs 6 are preferably stamped directly in the metal. I V

From the foregoing, itisseen thatthe radiator construction, according tothe present invention, eliminates the use or need of sideaplatesiand ofwelding operations as noted .hereabov thermore,-according to theinvention, ments l varemaintained at aconstant distance one from theother thereby maintaining the originalheat radiating efficiency of, theradiator and its neat general appearance. 7

It is obvious that the-device, according to the invention, =may be usedalso as cooling elements for refrigerating apparatus and for othersimilar uses. 7 While apreferred embodiment according tothe presentinvention has .been illustrated and described it is understood thatyarious modificaplate, a laterally and inwardly extending straightflange abutting'the next platefeach of said plates having a V-shapedgroove positioned inwardly from and running parallel with the edge ofsaid plates, the free edge of each flange entering the V-groove of theadjacent plate to prevent sidewise displacementof said free edge.

2. In a radiator having acentral conduit, heat radiating fins extendingfrom said conduit and consisting of relatively thin plates securedtransversely over the conduit in spaced parallel relation, each platehaving the marginal portion of 'two opp site; sides .bentiback uponitself :at. an acute angle itordefine inclined flanges adapted to abutthe adjacent. plate, each plate having :a V-groove formed parallel tothebentrfianges, and on the ,face of I the plate opposite said-flanges,each groove being so positioned as to receive snugly the fl'eeredge ofthe next-abutting flange,

the sides :of the groove preventing lateral movement of said free edge.
